Conveyor trough for chain conveyor belts, in particular Single chain scraper conveyor

The invention ^ "applies to a conveyor trough for chain scraper conveyor, in particular single-chain scraper conveyors made from gutter hooks each with a bracket profile connected to the side wall of the channel on the conveyor side facing away from the dismantling front for guiding a mining machine and a cable protection guide assigned to the Braoken profile. While the mining machine, for example, a cutting machine

can be, the cable protection guide is used to accommodate a The electrical cable leading to the cutting machine and possibly also other installations and exists regularly from several protective stirrups arranged one behind the other in the longitudinal direction of the channel at a specified distance. - Such a thing Conveyors are preferably used in long-front operations, often together with a shield support. Under Shield expansion is to be understood as a progressive pit expansion, which with the extraction machine and the conveyor the progressive dismantling follows on the dismantling front Lying sleepers with hydraulically or pneumatically extendable rams on which caps, especially at the front Wear pre-pledged caps to support the rock cover as close as possible to the mining front. With such a shield extension it is important to intercept the rock as close as possible to the mining front in order to ensure that the hanging wall is flawless and to avoid the collapse of mountains as much as possible. For this reason, the shield expansion is always moved as close as possible to the leading conveyor. However, the protruding reclining sleepers can be used prevent. These sleepers must namely be advanced to below the conveyor. Often they lie Recumbent sleepers, taking into account the local conditions, are so high on the recumbent that they in the course of advancing against the cable protection guide or Drive the brackish profile of the assigned channel section

and daduroh cause beaohtliohe damage. That applies in particular, taking into account the considerable back forces with whom the work is carried out when the Shield extension depending on the excavation site in direction is moved nautili on the dismantling front and thus against the conveyor. - The invention wants to avoid these Naohteile.

The invention is based on the object of providing a conveyor trough for * chain scraper conveyors, in particular single chain scraper conveyors, to sohaffen, in which the prone waves of a stepping pit construction in the course of the Np.ohrüokens itself in the elevated position against the lying surface are as it were automatically deflected in such a way that the brackish profile and the cable protection guide of the assigned gutter shot are no longer subject to damage.

This object is achieved by the invention with a conveyor trough for * chain scraper conveyors, in particular single chain scraper conveyors,

of the type described at the outset in that each gutter bottom in the transition area from the protective cable guide to the Brac '": enprofil inward, i.e. sliding sheet metal inclined against the Braoken profile to repel the prone waves of a striding Having pit lining against the lying. A walking or to understand shield expansion. - These measures of the invention have the consequence that the lying thresholds of the vor- or naohrüokenden pit expansion now at high altitude

against the sliding sheet of the assigned gutter base \. drive and consequently, as it were, independently against the lying: be distracted or slid into place. Damage to the cable protection .zführung as well as the Braoken profile is excluded. \

Further features essential to the invention are listed below. The invention provides that at least two sliding sheets are arranged at a predetermined distance from each other on each channel socket so that they are on the one hand in the central area of the horizontal shafts and on the other hand in the area of action of the fastening means for the pit lining. This ensures that the Lying thresholds during the Nachrüokens drive of the mine expansion at Hoohlage tat · säohlioh against Gleitbleohe and are deflected against the Liegen- \ en. According to a preferred embodiment of the invention, which is of independent importance, it is provided that the Gleitbleohe form brackets with the cable protection guide reaching under the support plates to support the cable protection guide and the consoles with the Brackenprofil Sohutzzimmer for electrical installations, also for the partial accommodation of the cutting machine or another extraction machine leading electrical cable. Other electrical installations are those for auxiliary drives, motors, lights, telephones, etc. : In any case, care is now taken to ensure that the electrical installations carried along are in a shelter: and are also protected against damage from lumps of stone and coal. In addition, the consoles take care of it

for additional stability in the transition area of the cable protection guide to the Braoken profile, as cable protection guide and Brackenprofile are now connected to one another in two fastening levels.

The advantages achieved by the invention are essentially to be seen in the fact that a conveyor trough for chain scraper conveyor, in particular single-chain scraper conveyor, is realized, in which case damage to the cable protection guide and the brackish profile can be excluded due to sliding plates arranged in their transition area. Because these sliding plates ensure that the lying sleepers of the subsequent pit support, especially Schreitoder Sohildausbaus, with appropriate Hoohiage against the Lying distracted and properly classified. In addition, there are additional protective rooms for electrical Installations created. Overall, there is an improved stability in relation to the cable protection guide and 3rackenprofil reached at each channel section.

In the following the invention is explained in more detail with reference to a drawing showing only one embodiment show it
